How can communication wires and power supply wires be separated? I. Check the signs Education: Wires cannot be picked up just by wanting to do so. Power poles usually have markings on them, indicating things like “Certain kilovolts, certain line, certain branch, pole number.” On some poles used for communication or broadcast cables, the inscriptions “Communication Lines” or “Radio and Television Lines” are also marked on the pole itself. II. Consider the height Science tip: Wires can’t be lifted just by wanting to do so. Power lines are usually installed at the top of utility poles, which are typically 8 meters or 10 meters tall – clearly much taller than the 6-meter communication poles! III. Check the configuration Explanation: Wires cannot be lifted just by wanting to do so. On power poles, there are insulators and other fittings such as crossarms that serve to provide support and insulation protection ； A certain gap should be maintained between the phase wires, which should be arranged neatly and parallel to each other ； Communication and broadcasting lines are generally not available. Communication lines are often bundled in the upper-middle part of the poles, crisscrossing each other. There is another common scenario: communication cables are installed in the middle section of existing utility poles, utilizing those poles for support. The several sets of “parallel lines” mounted above the pole as shown in the image above are power supply wires, while those bundled together below are communication cables. Furthermore, there is an extremely rare situation – the breakage of high-voltage transmission towers. Although the probability of this happening is extremely low, once you notice a broken cable or a toppled tower, be sure to stay as far away as possible and call 95598 immediately. Of course, the best approach is this: regardless of whether it’s a communication cable that has fallen, for safety reasons, it’s best to call the relevant communication company to report the issue or alert the authorities.
